Abstract

Graphite serves as the neutron moderator of British Gas-Cooled Reactors and is a candidate material for the Generation IV of nuclear power stations. The neutron irradiation affects the crystalline structure of graphite; this damage results in volumetric changes of the bulk material and generation of porosity. Dimensional changes induced by irradiation in graphite bricks can make difficult the refueling operations and reduce the stability of the graphite core. Some of the neutron irradiation damage mechanisms in the crystal lattice of graphite are not well understood. Results of TEM, SEM, FIB-SEM tomography, gas adsorption and optical microscopy will be combined to help understand how the irradiation affects graphite at multiple length scales. Furthermore, some new evidence of porosity and microstructural changes generated by irradiation will be presented.
